Mileto (Calabrian: Militu; Ancient Greek: Μίλητος, romanized: Míletos) is a comune (municipality) in the Province of Vibo Valentia in the Italian region Calabria, located about 60 kilometres (37 mi) southwest of Catanzaro and about 6 kilometres (4 mi) south of Vibo Valentia.
Roger's son and also a Count of Sicily, Simon died in the town in 1105, when he was 12 years old.
He began his rule as Count of Sicily in 1105 and later became Duke of Apulia and Calabria in 1127.
In 1807 it was the location of the Battle of Mileto between the French and Neapolitan armies.
Mileto suffered from numerous earthquakes, especially from those of 1905 and 1906, and, although in a less degree, from that of 28 December 1908, which destroyed Reggio and Messina.
